The direction will be described as the stacking direction Z (see FIG. 1).

In the following embodiments, the vertical direction in a state where the electrolytic liquid generation device is arranged so that the electrode case lid is on the upper side is defined as the stacking direction Z.

(First Embodiment)

(See FIG. 3). It is sufficient that at least one groove 52 is formed in the laminated body 51.

By forming the groove 52 in the laminated body 51, water supplied from the inflow port 111 into the channel 11 can be introduced into the groove 52. Then, ozone water in which ozone is dissolved as an electrolysis product is generated by subjecting the water introduced into the groove 52 mainly to an electrolytic treatment for causing an electrochemical reaction.

The housing 10 is formed using a non-conductive resin such as PPS (Polyphenylenesulfide). In the present embodiment, the housing 10 includes the electrode case 20 and the electrode case lid 40. The electrode case 20 has a concave portion 23 which is open upward and accommodates the electrolytic portion 50. The electrode case cover 40 covers the opening of the electrode case 20.

As shown in FIG. 1, the electrode case 20 includes a bottom wall portion 21 and a peripheral wall portion 22 connected to a peripheral portion of the bottom wall portion 21, and has a substantially box-like shape that opens upward. I have. That is, the electrode case 20 is formed with the inner surface 21 a of the bottom wall portion 21 and the inner surface 22 a of the peripheral wall portion 22, and has a concave portion 23 that opens upward.

電解 Then, the electrolytic portion 50 is housed in the concave portion 23 by introducing the electrolytic portion 50 into the concave portion 23 from the opening side (upper side). The opening of the concave portion 23 is formed so as to be larger than the outline shape of the electrolytic portion 50 as viewed in the laminating direction Z, and the laminating direction matches the vertical direction (laminating direction Z). 50 can be inserted into the recess 23 in the same posture.

Furthermore, in the present embodiment, electrolytic portion 50 is housed in recess 23 via elastic body 60. That is, the electrolysis unit 50 is housed in the recess 23 while the elastic body 60 is interposed between the electrolysis unit 50 and the electrode case 20 and the elastic body 60 is in contact with the lower surface 50 b of the electrolysis unit 50. Have been. The elastic body 60 is formed using an elastic material such as rubber, plastic, and a metal spring.

In the present embodiment, when the electrode case cover 40 is attached to the electrode case 20, the flow path 11 is formed between the electrolytic section 50 and the electrode case cover 40. The flow channel 11 may be formed such that the cross-sectional area (the area of the flow channel 11 when cut along a plane perpendicular to the liquid flow direction X) at a portion facing the electrolytic unit 50 is substantially the same at a plurality of positions. preferable.

The electrode case lid 40 includes a substantially rectangular plate-shaped lid body 41 and a projection 42 projecting downward from the lower center of the lid body 41 and inserted into the recess 23 of the electrode case 20. I have.

(4) A fitting recess 411 for welding is formed over the entire periphery of the lid body 41 at the periphery of the projection 42. When the electrode case lid 40 is attached to the electrode case 20, a welding fitting protrusion 241 formed around the entire periphery of the opening of the electrode case 20 is inserted into the fitting recess 411 (FIG. 2).

In the present embodiment, a flange portion 24 extending substantially horizontally outward is continuously provided on the entire periphery at the upper end of the peripheral wall portion 22 of the electrode case 20. A fitting projection 241 projecting upward is formed on the flange 24 so as to surround the opening of the electrode case 20. Then, the electrode case lid 40 and the electrode case 20 are welded with the fitting projection 241 inserted into the fitting recess 411 while the projection 42 is inserted into the recess 23.

The electrode case cover 40 may be attached to the electrode case 20 by screwing the electrode case cover 40 to the electrode case 20 with a sealing material interposed between the electrode case cover 40 and the electrode case 20. It is possible.

突起 A projection 421 for pressing the electrolytic portion 50 downward is formed at both ends and a center of the lower surface side of the projection 42 in the width direction Y. When the electrolytic portion 50 is accommodated in the concave portion 23 via the elastic body 60 and the electrode case cover 40 is attached to the electrode case 20, the electrolytic portion 50 is lowered by the projection 421 provided on the electrode case cover 40.

As described above, in the present embodiment, when the electrolytic section 50 is pressed downward, a constant pressure is applied to the entire electrolytic section 50 by the elastic body 60. Thereby, the adhesiveness of each member constituting the electrolysis unit 50 can be further enhanced.

In the present embodiment, a plurality of through-holes 61 penetrating in the stacking direction Z are formed in the elastic body 60 along the longitudinal direction (the liquid passing direction X). Thereby, when pressed by the electrolytic part 50, the elastic body 60 can also be deformed to the through hole 61 side. As described above, by deforming the elastic body 60 also toward the through hole 61, the compression of the electrode case 20 by the elastic body 60 pressed by the electrolytic unit 50 is suppressed.

In the present embodiment, the groove 412 is provided on the upper surface of the lid main body 41. The groove 412 can be used for positioning, catching, preventing reverse insertion, and the like when fixing the ozone water generation device 1. By providing the groove 412, the ozone water generation device 1 can be more easily and erroneously incorporated into a device that requires ozone generation.

The ozone water generator 1 is used in a state where it is incorporated in other equipment and facilities. When assembling the ozone water generating apparatus 1 into other equipment and facilities, it is preferable to arrange the ozone water generating apparatus 1 in an upright state so that the inflow port 111 is located downward and the outflow port 112 is located upward. By arranging the ozone water generating device 1 so that the inflow port is located downward and the outflow port is located upward, ozone generated at the electrode interface can be quickly separated from the electrode interface by buoyancy. That is, ozone generated at the electrode interface can be quickly separated from the electrode interface before bubble growth. As a result, ozone is easily dissolved in water, and the efficiency of generating ozone water is improved. Note that the arrangement state of the ozone water generation device 1 is not limited to this, and can be appropriately arranged.

The power supply shaft 53b is inserted into a through hole 211 formed at one end of the bottom wall 21 in the liquid flow direction X. A portion of the power supply shaft 53b protruding outside the electrode case 20 is electrically connected to a positive electrode of a power supply unit (not shown).

The anode 54 is formed, for example, by forming a conductive diamond film on a conductive substrate having a size of about 10 mm in width and about 100 mm in length formed using silicon. Further, for example, two sheets each having a size of about 10 mm in width and about 50 mm in length may be formed side by side. The conductive diamond film has Borundov conductivity. The conductive diamond film is formed on a conductive substrate with a thickness of about 3 μm by a plasma CVD method.

The conductive film 56 is disposed on the anode 54 on which the conductive diamond film is formed. The conductive film 56 is a proton conductive type ion exchange film and has a thickness of about 100 to 200 μm. The conductive film 56 has a plurality of conductive film side holes (conductive film side grooves) 56c penetrating in the thickness direction (stacking direction Z) (see FIG. 5).

In the present embodiment, each conductive film side hole 56c has substantially the same shape. Specifically, each conductive film side hole 56c has a long and narrow hole shape in the width direction Y. The plurality of conductive film side holes 56c are provided so as to be arranged in a line at a predetermined pitch in the longitudinal direction (liquid flowing direction X). The shape and arrangement of the conductive film side holes 56c may be different from the example shown in FIG. In addition, at least one conductive film side hole 56c may be formed.

The negative electrode 55 is disposed on the conductive film 56. The cathode 55 is made of, for example, a titanium electrode plate having a thickness of about 0.5 mm. A cathode power supply shaft 55b is electrically connected to the other end of the cathode 55 in the longitudinal direction (downstream in the liquid passing direction X) via a spiral spring portion 55a. The power supply shaft 55b is inserted into a through hole 211 formed on the other end of the bottom wall 21 in the liquid passing direction X. A portion of the power supply shaft 55b protruding outside the electrode case 20 is electrically connected to a negative electrode of a power supply unit (not shown).

複数 Further, a plurality of cathode-side holes (cathode-side groove portions: electrode-side groove portions) 55e penetrating in the thickness direction are formed in the cathode 55 (see FIG. 6). In the present embodiment, each cathode side hole 55e has substantially the same shape. Specifically, each cathode side hole 55e has a V-shape in which a bent portion 55f is disposed on the downstream side in plan view.

(4) The plurality of cathode-side holes 55e are provided so as to be arranged in a line at a predetermined pitch along the longitudinal direction (liquid flowing direction X).

The pitch of the cathode side holes 55e may be the same pitch as the conductive film side holes 56c, or may be different from the conductive film side holes 56c. Further, the shape and arrangement of the cathode side holes 55e may be different from the example of FIG. Further, at least one cathode side hole 55e may be formed.

By doing so, even if the conductive film 56 is relatively displaced with respect to the cathode (electrode) 55 in the direction intersecting the stacking direction Z, the contact between the conductive film 56 and the cathode (electrode) 55 A change in area can be suppressed. Note that the shape (contour shape and size) of the conductive film side hole 56c and the cathode side hole 55e in plan view can be the same.

When the conductive film 56 and the cathode 55 are stacked, at least a part of the mutual holes (the cathode side hole 55e and the conductive film side hole 56c) needs to communicate with each other. A sufficient contact area must be ensured. As long as the above conditions are satisfied, the conductive film 56 and the cathode 55 may have the same projected size (size in plan view) or may have different projected sizes.

In the present embodiment, the width of the cathode 55 in the width direction Y is larger than that of the conductive film 56 (see FIG. 3).

The projected size of the anode 54 may be the same size as at least one of the conductive film 56 and the cathode 55 or may be different, but when stacked, the conductive film side hole 56c is closed from below. It is preferably of a size that can be used.

In the present embodiment, the anode 54 and the conductive film 56 have substantially the same projected dimensions.

In addition, it is preferable that the power supply 53 can efficiently supply electricity to the anode 54, and the elastic body 60 has a projected size enough to be pressed by the entire lower surface of the power supply 53 (the lower surface 50 b of the electrolytic unit 50). It is preferable that

In the present embodiment, the dimension of the power supply 53 in the width direction Y is smaller than that of the anode 54 and the conductive film 56, and the dimension of the elastic body 60 in the width direction Y is substantially equal to that of the anode 54 and the conductive film 56. The projection dimensions are the same. The projection dimensions of the power supply 53 and the elastic body 60 can be various dimensions.

電解 The electrolytic unit 50 having such a configuration can be accommodated in the concave portion 23 of the electrode case 20 by, for example, a method described below.

First, the power supply 53 is arranged on the elastic body 60 inserted into the recess 23 of the electrode case 20. Specifically, the power supply body 53 is inserted into the concave portion 23 of the electrode case 20 with the tip of the power supply shaft 53b facing downward. Then, the power supply body 53 is stacked on the elastic body 60 by inserting the power supply shaft 53b into the one through hole 211.

Next, the anode 54 is inserted into the recess 23 of the electrode case 20 and laminated on the power supply 53.

Next, the conductive film 56 is inserted into the recess 23 of the electrode case 20 and laminated on the anode 54.

Next, the cathode 55 is inserted into the recess 23 of the electrode case 20 with the tip of the power supply shaft 55b facing downward while the power supply shaft 55b is inserted into the other through-hole 211, so that the cathode 55 is It is laminated on the conductive film 56.

Next, an O-ring 31, a washer 32, and a washer are provided on a portion of the anode power supply shaft 53b protruding outside the electrode case 20 and on a portion of the cathode power supply shaft 55b protruding outside the electrode case 20, respectively. 33 and hex nut 34 are inserted.

The electrolytic portion 50 is housed and fixed in the recess 23 while being pressed against the elastic body 60 by tightening the hexagon nut 34.

In the present embodiment, by moving the electrode case lid 40 relative to the electrode case 20 in the stacking direction Z, the projection 42 is inserted into the recess 23 while being fitted into the fitting recess 411 for welding. The collision part 241 is inserted.

As described above, the ozone water generation device 1 according to the present embodiment is assembled simply by moving each member relatively to the electrode case 20 in the vertical direction (the stacking direction Z).

Next, the operation and action of the ozone water generation device 1 will be described.

First, in order to supply water to the ozone water generator 1, water is supplied from the inlet 111 to the channel 11. Part of the water supplied to the flow channel 11 flows into the groove 52 and comes into contact with the interface 57 and the interface 58 of the groove 52.

で In such a state (a state in which the electrolytic unit 50 is immersed in the supplied water), a voltage is applied between the anode 54 and the cathode 55 of the electrolytic unit 50 by a power supply unit (not shown). Then, a potential difference is generated between the anode 54 and the cathode 55 via the conductive film 56. By generating a potential difference between the anode 54 and the cathode 55, the anode 54, the conductive film 56, and the cathode 55 are energized, and the electrolytic treatment is performed mainly in the water in the groove 52. Ozone is generated in the vicinity of the interface 57 with the ozone.

Ozone generated near the interface 57 between the conductive film 56 and the anode 54 dissolves in the water while being carried to the downstream side of the flow path 11 along the flow of the water. As described above, dissolved ozone water (ozone water: electrolytic liquid) is generated by dissolving ozone in water.

The ozone water generating apparatus 1 can be applied to an electric device using the electrolytic liquid generated by the electrolytic liquid generating apparatus, a liquid reforming apparatus including the electrolytic liquid generating apparatus, and the like.

Examples of electric equipment and liquid reforming equipment include water treatment equipment such as water purification equipment, washing machines, dishwashers, hot water washing toilet seats, refrigerators, hot and cold water supply equipment, sterilization equipment, medical equipment, air conditioning equipment, and kitchens. Equipment.

According to the present embodiment, compression of peripheral wall portion 22 (housing 10) and electrolytic portion 50 by the scale generated by the electrolysis of water is suppressed.

Specifically, a space S is formed between the outer peripheral portion of at least one of the cathode 55 and the anode 54 and the inner surface 22a of the peripheral wall portion 22 (the inner surface of the housing 10). Is prevented from staying around the surrounding area.

That is, by actively providing the space S for flowing water between the periphery of the electrolysis unit 50 and the peripheral wall portion 22 (housing 10), the stagnation of water around the electrolysis unit 50 can be suppressed. The space portion S has a gap larger than a manufacturing tolerance generated when assembling the ozone water generation device 1.

In the present embodiment, as described above, the width of the cathode 55 in the width direction Y is larger than that of the conductive film 56. The anode 54 and the conductive film 56 have substantially the same projected dimensions.

(4) When the laminated body 51 is formed, both ends of the cathode 55 in the width direction Y protrude outside the anode 54 and the conductive film 56.

That is, the outer peripheral portion (side surface) 55c of the cathode 55 protrudes outside the outer peripheral portion (side surface) 54a of the anode 54 in the width direction Y (the direction intersecting the stacking direction Z). A portion of the cathode 55 that protrudes outside the outer peripheral portion 54a of the anode 54 in the width direction Y is referred to as a cathode-side protruding portion 55g (see FIG. 3).

As described above, when the cathode-side protruding portions 55g that protrude outside the anode 54 and the conductive film 56 are formed at both ends in the width direction Y of the cathode 55, when the stacked body 51 is accommodated in the concave portion 23, the peripheral wall portion is formed. A space S is formed between the inner surface 22 a of the anode 22 and the anode 54. A space S is also formed below the cathode-side projection 55g of the cathode 55 (on the anode 54 side in the stacking direction Z).

In the present embodiment, the space portion S is an anode-side space portion (second space portion) formed between the outer peripheral portion (side surface) 54a of the anode 54 and the inner surface (inner surface of the housing 10) 22a of the peripheral wall portion 22. S2 is provided. Further, the space S has a lower space (third space) S3 formed on the anode 54 side in the stacking direction Z with respect to the cathode 55.

Further, in the present embodiment, with the cathode-side protruding portion 55g formed, the manufacturing tolerance is also provided between the outer peripheral portion (side surface) 55c of the cathode 55 and the inner surface (inner surface of the housing 10) 22a of the peripheral wall portion 22. A larger gap is provided. That is, the space portion S has a cathode-side space portion (first space portion) S1 formed between the outer peripheral portion (side surface) 55c of the cathode 55 and the inner surface (inner surface of the housing 10) 22a of the peripheral wall portion 22. ing.

As described above, in the present embodiment, between the outer peripheral portion (side surface) 51a of the multilayer body 51 and the inner surface 22a of the peripheral wall portion 22, the cathode space portion (first space portion) S1 and the anode space portion (first space portion) are provided. A space S having a second space S2 and a lower space (third space) S3 is formed.

In the present embodiment, the space S is formed at least around the longitudinal direction of the stacked body 51. That is, at least a portion of the cathode-side space (first space) S1 is formed along the side surface 51a. The side surfaces 51a are arranged on both sides in the width direction Y of the multilayer body 51 and extend in the longitudinal direction (liquid flow direction X).

The cathode side space (first space) S1 communicates with the inflow port 111 and the outflow port 112, and the water introduced into the cathode side space (first space) S1 flows out of the outflow port 112 efficiently. Although it is preferable to make it communicate, it may be made to communicate in the middle of the channel 11.

形成 By forming such a space portion S, it is possible to suppress the scale formed by the electrolysis of water, such as a calcium component, from accumulating between the laminate 51 and the peripheral wall portion 22.

For example, the vicinity of the interface 58 between the conductive film 56 and the cathode 55 is a portion where the pH value is likely to increase and scale is likely to occur, but if the space S described in the present embodiment is formed, A relatively large space is formed near the interface 58. That is, the outer interface 58 in the width direction Y forms a space (lower space portion (third space portion) S3) of a predetermined size on the anode 54 side (lower side) in the stacking direction Z and has a width In a state where a space (anode-side space (second space) S2) having a predetermined size is formed outside the direction Y, the space S is exposed.

Furthermore, in the present embodiment, the outer interface 58 in the width direction Y is exposed to the space S along the longitudinal direction (the liquid passing direction X), and the outer interface 58 in the width direction Y is substantially The whole is exposed to the space S.

ため Therefore, the water introduced into the space S flows downstream along the liquid flowing direction X. That is, the water introduced near the interface 58 exposed to the space S also flows relatively quickly to the downstream side along the liquid flowing direction X. Therefore, the scale generated near the interface 58 can flow downstream before being fixed to the laminate 51 and the housing 10. In this manner, if the space S shown in the present embodiment is formed, water is prevented from staying in the vicinity of the interface 58 where scale is likely to occur, and the scale generated in the vicinity of the interface 58 is It can quickly flow downstream. As a result, accumulation of scale between the laminate 51 and the peripheral wall 22 is suppressed. Therefore, it is possible to prevent the peripheral wall portion 22 (housing 10) and the electrolytic portion 50 from being pressed by the scale.

If the space S is provided, accumulation of scale between the laminate 51 and the peripheral wall 22 is suppressed, but the laminate 51 and the peripheral wall 22 have a relatively small amount, The scale sticks. Therefore, when the ozone water generation device 1 is used for a long time, the scale fixed to the laminate 51 and the peripheral wall 22 becomes large, and the peripheral wall 22 (housing 10) and the electrolytic unit 50 may be pressed. There is also. For this reason, the size of the space S may be set to such a size that the space S is not blocked by the fixed scale even when the ozone water generation device 1 is used for the expected life or longer by a normal method. preferable. Typical usage methods are, for example, water quality (liquid quality) of water supplied into the housing, average flow velocity and average flow rate of water flowing in the housing, ozone generation efficiency (voltage applied between electrodes and electrolytic area). , And the expected use frequency.

A plurality of positioning protrusions 221 extending in the vertical direction (stacking direction Z) are formed inside the peripheral wall portion 22 of the electrode case 20 along the longitudinal direction (liquid flow direction X) (see FIG. 4). ). Then, the displacement of the anode 54 at the time of lamination is suppressed by the positioning projection 221 (see FIG. 4). In the present embodiment, the positioning protrusion 221 is formed on the inner surface of the peripheral wall portion 22 (the inner surface of the housing) at a position facing the outer peripheral portion 51a of the laminate 51. The positioning protrusion 221 corresponds to a housing protrusion protruding toward the stacked body 51.

By forming the positioning projections (housing projections) 221 on the peripheral wall portion 22, the outer peripheral portion (side surface) 51 a of the laminated body 51 and the inner surface 22 a of the peripheral wall portion 22 can be formed simply by disposing the laminate 51 in the concave portion 23. A space S is formed therebetween.

In the present embodiment, a conductive film-side concave portion 56b as a relief portion is formed in a concave shape on the outer peripheral portion (side surface) 56a (contour line in a plane) of the conductive film 56 (see FIG. 5). The conductive film-side concave portion 56b is formed at a position corresponding to the positioning protrusion (housing protrusion) 221 when the laminated body 51 is disposed in the concave portion 23.

Therefore, when the conductive film 56 is inserted into the concave portion 23 and laminated on the anode 54, the concave portion 56b of the conductive film side facing the concave portion faces the positioning protrusion 221 of the peripheral wall portion 22 (see FIG. 5). Accordingly, it is possible to prevent the conductive film 56 expanded including water from interfering with the positioning protrusion 221 at the time of generation of ozone water or the like.

In addition, a cathode-side concave portion 55d as a relief portion is formed in a concave shape also on an outer peripheral portion (side surface) 55c (a contour line in a plan view) of the cathode 55 having a width larger in the width direction Y than the conductive film 56 (see FIG. See FIG. 6). The cathode-side concave portion 55d is formed at a position corresponding to the positioning protrusion (housing protrusion) 221 when the stacked body 51 is disposed in the concave portion 23.

Therefore, when the cathode 55 is inserted into the recess 23 and laminated on the conductive film 56, the concave cathode-side recess 55d faces the positioning projection 221 of the peripheral wall 22 (see FIG. 6). This suppresses interference of the cathode 55 having a larger dimension in the width direction Y with the positioning protrusion 221. That is, the cathode-side recess 55d is formed so that the interference between the cathode 55 and the positioning protrusion 221 is suppressed while the surface area of the cathode 55 is increased as much as possible.

The space S may be formed between the outer peripheral portion of at least one of the cathode 55 and the anode 54 and the inner surface 22a of the peripheral wall portion 22 (the inner surface of the housing 10). 51 may be configured as shown in FIGS. 7 to 11, for example.

Hereinafter, a modified example of the space S of the present embodiment will be described.

First, FIG. 7 shows a stacked body 51 in which the outer peripheral portion (side surface) 56a of the conductive film 56 is projected more than the outer peripheral portion (side surface) 54a of the anode 54 in the width direction Y (direction intersecting with the laminating direction Z). Is disclosed. The portion of the conductive film 56 that protrudes beyond the outer peripheral portion 54a of the anode 54 in the width direction Y is defined as a conductive film-side protrusion 56d.

(7) Further, in FIG. 7, the cathode 55 and the conductive film 56 have substantially the same projected dimensions.

In this manner, in FIG. 7, the cathode 54 is formed at both ends in the width direction Y of the cathode 55, while the cathode-side protrusions 55 g projecting outside the anode 54 are formed at both ends in the width direction Y of the conductive film 56. A conductive film-side protruding portion 56d protruding outward is formed. In this way, when the stacked body 51 is accommodated in the concave portion 23, the cathode side space (first space) S1, between the outer peripheral portion (side surface) 51a of the stacked body 51 and the inner surface 22a of the peripheral wall portion 22, A space S having an anode-side space (second space) S2 and a lower space (third space) S3 is formed.

でも Even with such a configuration, accumulation of scale between the laminate 51 and the peripheral wall portion 22 can be suppressed.

Further, by expanding the conductive film 56 to both ends in the width direction Y of the cathode 55, the conductive film 56 also comes into contact with the lower surface of the cathode-side protruding portion 55g. Available. That is, the contact area (electrolysis area) between the cathode 55 and the conductive film 56 can be further increased.

Next, in FIG. 8, similarly to the laminate 51 described in the present embodiment, at both ends in the width direction Y of the cathode 55, the cathode-side projections 55g projecting outside the anode 54 and the conductive film 56 are shown. Is disclosed.

The outer peripheral portion (side surface extending in the longitudinal direction) 55c of the cathode 55 contacts the inner surface 22a of the peripheral wall portion 22, and the outer peripheral portion 54a of the anode 54, the outer peripheral portion 56a of the conductive film 56, and the inner surface 22a of the peripheral wall portion 22. A space S is formed between the two. That is, when the stacked body 51 is accommodated in the recess 23, the anode-side space (second space) S <b> 2 and the lower side are provided between the outer peripheral portion (side surface) 51 a of the stacked body 51 and the inner surface 22 a of the peripheral wall 22. A space S having a space (third space) S3 is formed.

In the configuration shown in FIG. 8 (the configuration in which the outer peripheral portion 55c of the cathode 55 is brought into contact with the inner surface 22a of the peripheral wall portion 22), the conductive film side protrusion 56d described in FIG. It is possible to form. However, if the conductive film-side protruding portion 56d is also brought into contact with the inner surface 22a of the peripheral wall portion 22, there is a possibility that water may stay between the interface 58 and the inner surface 22a of the peripheral wall portion 22 where scale is likely to occur. . Therefore, when forming the conductive film side protruding portion 56d, a gap (space S) between the outer peripheral portion 56a of the conductive film 56 and the inner surface 22a of the peripheral wall portion 22 that can suppress the accumulation of water is provided. Is preferably formed.

Next, FIG. 9 shows a laminate 51 in which at least portions extending in the longitudinal direction in the outer peripheral portion 54a of the anode 54, the outer peripheral portion 55c of the cathode 55, and the outer peripheral portion 56a of the conductive film 56 are substantially flush with each other. Is disclosed. The side surface 54 a extending in the longitudinal direction of the anode 54, the side surface 55 c extending in the longitudinal direction of the cathode 55, the side surface 56 a extending in the longitudinal direction of the conductive film 56, and the inner surface 22 a of the peripheral wall portion 22. A space S is formed between the two. That is, when the laminate 51 is accommodated in the recess 23, the cathode-side space portion (first space portion) S <b> 1 and the anode-side space portion are provided between the outer peripheral portion (side surface) 51 a of the laminate 51 and the inner surface 22 a of the peripheral wall portion 22. A space S having a space (second space) S2 is formed.

Next, FIG. 10 discloses a stacked body 51 in which the size of the anode 54 in the width direction Y is larger than that of the conductive film 56 and the cathode 55 and the conductive film 56 have substantially the same projected dimensions. I have.

Then, when the laminated body 51 is formed, both ends of the anode 54 in the width direction Y are projected outside the cathode 55 and the conductive film 56, and the width of the anode 54 in the width direction Y is larger than the outer peripheral portion 55 c of the cathode 55. The part protruding outside is defined as the anode-side protruding part 54b.

As described above, by forming the anode-side protruding portions 54 b protruding outside the cathode 55 and the conductive film 56 at both ends in the width direction Y of the anode 54, when the stacked body 51 is accommodated in the concave portion 23, the peripheral wall A space S is formed between the inner surface 22a of the portion 22 and the cathode 55. A space S is also formed above the anode-side protruding portion 54b of the anode 54 (on the side of the cathode 55 in the stacking direction Z).

In this manner, in FIG. 10, the space S is formed between the outer peripheral portion (side surface) 55 c of the cathode 55 and the inner surface (inner surface of the housing 10) 22 a of the peripheral wall 22 (the first space). Part) S1. The space S also has an upper space (fourth space) S4 formed closer to the cathode 55 in the stacking direction Z than the anode 54.

Further, in FIG. 10, a gap exceeding the manufacturing tolerance is provided between the outer peripheral portion (side surface) 54a of the anode 54 and the inner surface (inner surface of the housing 10) 22a of the peripheral wall portion 22 in a state where the anode-side protruding portion 54b is formed. Is provided. That is, the space portion S has an anode-side space portion (second space portion) S2 formed between the outer peripheral portion (side surface) 54a of the anode 54 and the inner surface (inner surface of the housing 10) 22a of the peripheral wall portion 22. ing.

As described above, in FIG. 10, between the outer peripheral portion (side surface) 51a of the laminate 51 and the inner surface 22a of the peripheral wall portion 22, the cathode side space portion (first space portion) S1 and the anode side space portion (second space portion) Part S2 and a space part S having an upper space part (fourth space part) S4.

In the configuration shown in FIG. 10, the conductive film side protruding portion 56d described in FIG. 7 can be formed on the conductive film 56. That is, at both ends in the width direction Y of the anode 54, the anode-side protrusions 54 b protruding outside the cathode 55 are formed, and at both ends in the width direction Y of the conductive film 56, the protrusions protrude outside the cathode 55. The conductive film side protrusion 56d can be formed.

Further, by expanding the conductive film 56 to both ends in the width direction Y of the anode 54, the conductive film 56 also contacts the upper surface of the anode-side protruding portion 54b. Available. That is, the contact area (electrolysis area) between anode 54 and conductive film 56 can be further increased.

Next, in FIG. 11, similarly to the stacked body 51 described with reference to FIG. 10, at both ends in the width direction Y of the anode 54, the anode-side protruding portions 54b projecting outside the cathode 55 and the conductive film 56 are formed. A stacked body 51 is disclosed.

Then, the outer peripheral portion (side surface extending in the longitudinal direction) 54 a of the anode 54 contacts the inner surface 22 a of the peripheral wall portion 22, and the outer peripheral portion 55 c of the cathode 55, the outer peripheral portion 56 a of the conductive film 56, and the inner surface of the peripheral wall portion 22. The space S is formed between the space S and the space 22a. That is, when the laminate 51 is accommodated in the recess 23, the cathode-side space (first space) S <b> 1 and the upper space are provided between the outer peripheral portion (side surface) 51 a of the laminate 51 and the inner surface 22 a of the peripheral wall portion 22. A space portion S having a portion (fourth space portion) S4 is formed.

In the configuration shown in FIG. 11 (the configuration in which the outer peripheral portion 54a of the anode 54 is in contact with the inner surface 22a of the peripheral wall portion 22), the conductive film-side protruding portion 56d described in FIG. It is possible to do. However, if the conductive film side protruding portion 56 d is also brought into contact with the inner surface 22 a of the peripheral wall portion 22, there is a possibility that water may stagnate between the interface 58 and the inner surface 22 a of the peripheral wall portion 22 where scale is likely to occur. Therefore, when forming the conductive film side protruding portion 56d, a gap (space S) between the outer peripheral portion 56a of the conductive film 56 and the inner surface 22a of the peripheral wall portion 22 that can suppress the accumulation of water is provided. Is preferably formed.

As described above, the ozone water generation device (electrolytic liquid generation device) 1 according to the present embodiment is configured such that the conductive film 56 is interposed between the anode 54 and the cathode 55 (between adjacent electrodes). It has a stacked body 51 and is provided with an electrolysis section 50 for electrolyzing water (liquid). Further, the ozone water generation device 1 includes the housing 10 in which the electrolysis unit 50 is disposed.

The housing 10 has an inlet 111 into which water supplied to the electrolytic unit 50 flows, and an outlet 112 from which ozone water (electrolyzed water: electrolytic liquid) generated in the electrolytic unit 50 flows out. The flow path 11 is formed in which the direction X intersects with the stacking direction Z of the stacked body 51.

In the electrolysis part 50, at least a part of an interface 57 between the conductive film 56 and the electrode (anode 54) and an interface 58 between the conductive film 56 and the electrode (cathode 55) is opened in the flow channel 11. An exposed groove 52 is formed.

In the present embodiment, the electrodes adjacent to each other are the cathode 55 and the anode 54, and the outer periphery of at least one of the cathode 55 and the anode 54 and the inner surface (inner surface of the housing) 22 a of the peripheral wall 22. A space S that suppresses stagnation of water is formed therebetween.

The space S may have a cathode-side space (first space) S1 formed between the outer peripheral portion 55c of the cathode 55 and the inner surface (inner surface of the housing) 22a of the peripheral wall 22. .

In addition, the space S may have an anode-side space (second space) S2 formed between the outer peripheral portion 54a of the anode 54 and the inner surface (inner surface of the housing) 22a of the peripheral wall 22. .

The space S may have a lower space (third space) S3 formed closer to the anode 54 in the stacking direction Z than the cathode 55 is.

れば If such a space S is formed around the electrolysis unit 50, it is possible to prevent water from staying around the electrolysis unit 50. Then, if water is prevented from staying around the electrolysis unit 50, the adhesion of the scale to the periphery of the electrolysis unit 50 and the peripheral wall 22 (the housing 10) is suppressed.

Further, even if the scale is fixed to the periphery of the electrolytic portion 50 and the peripheral wall portion 22, the space S is formed between the electrolytic portion 50 and the peripheral wall portion 22, so that the electrolytic portion 50 and the peripheral wall portion 22 are formed. Compression by the scale 22 is suppressed, and deformation (bending or the like) of the electrolytic unit 50 is suppressed. When the deformation of the electrolytic section 50 is suppressed, the contact between the anode 54 and the conductive film 56 and the contact between the conductive film 56 and the cathode 55 are prevented from becoming uneven. That is, the anode 54 and the conductive film 56 can be more uniformly contacted, and the conductive film 56 and the cathode 55 can be more uniformly contacted.

In this way, if the space S is formed between the electrolysis part 50 and the peripheral wall part 22, the deformation of the electrolysis part 50 due to the scale being fixed is suppressed, and the contact of the laminate 51 in the electrolysis part 50 is reduced. Can be more even. Then, by making the contact of the stacked body 51 more uniform, a current-carrying area (for example, an electrolysis area between the conductive film 56 and the cathode 55) can be more stably secured. If the current-carrying area can be more stably secured, the current density of the current flowing through the electrolytic unit 50 can be made more uniform, and the generation efficiency of ozone (electrolysis product) can be further stabilized. Can be done.

As described above, according to the present embodiment, it is possible to obtain the ozone water generation device 1 that can suppress the compression of the peripheral wall portion 22 (housing 10) and the electrolytic portion 50 by the scale.

The outer peripheral portion 55c of the cathode 55 may be made to protrude more than the outer peripheral portion 54a of the anode 54 in the width direction Y (a direction intersecting the stacking direction Z).

In this case, the area of the cathode 55 is increased by an amount corresponding to the projection in the width direction Y from the outer peripheral portion 54a of the anode 54, so that the current density of the current flowing through the cathode 55 is reduced and the periphery of the cathode 55 is electrolyzed. Accumulation of the generated scale can be suppressed.

{Circle around (4)} The outer peripheral portion 56a of the conductive film 56 may be made to protrude more than the outer peripheral portion 54a of the anode 54 in the width direction Y (the direction intersecting the stacking direction Z).

でも This also suppresses the pressure of the electrolytic section 50 and the peripheral wall section 22 due to the scale, so that the generation efficiency of ozone (electrolysis product) can be further stabilized.

Further, if the size of the cathode 55 and the conductive film 56 in the width direction Y is made larger than that of the anode 54, the conductive film 56 also comes into contact with the lower surfaces of both ends in the width direction Y of the cathode 55, so that the size is increased. The area of the cathode 55 can be used more effectively. That is, the contact area (electrolysis area) between the cathode 55 and the conductive film 56 can be further increased.

The space S may be formed at least around the longitudinal direction of the laminate 51.

In this way, the stagnation of water around the electrolytic section 50 can be more reliably suppressed, and the ozone (electrolysis product) generation efficiency can be further stabilized.

Further, a positioning projection (housing projection) 221 projecting toward the laminate 51 may be formed on a portion of the inner surface (inner surface of the housing) 22a of the peripheral wall portion 22 facing the outer peripheral portion 51a of the laminate 51. .

In this case, the space S can be formed between the outer peripheral portion (side surface) 51 a of the laminated body 51 and the inner surface 22 a of the peripheral wall portion 22 only by disposing the laminated body 51 in the concave portion 23. Therefore, a gap (space S) can be more reliably secured between the laminate 51 and the peripheral wall 22.

The cathode-side concave portion 55d may be formed at a position corresponding to the positioning projection (housing projection) 221 on the outer peripheral portion 55c of the cathode 55.

In this way, it is possible to suppress the cathode 55 from interfering with the positioning projection (housing projection) 221 when the cathode 55 is disposed in the recess 23. For this reason, the cathode 55 whose surface area is increased as much as possible can be arranged in the recess 23.

The conductive film side concave portion 56b may be formed at a position corresponding to the positioning protrusion (housing protrusion) 221 on the outer peripheral portion 56a of the conductive film 56.

In this way, it is possible to prevent the conductive film 56 swelled with water at the time of generation of ozone water or the like from interfering with the positioning projection (housing projection) 221. That is, it is possible to suppress the expanded conductive film 56 from being deformed by interfering with the positioning projection (housing projection) 221. As a result, the contact of the stacked body 51 can be made more uniform, and the generation efficiency of ozone (electrolysis product) can be further stabilized.

Although the preferred embodiment of the present disclosure has been described above, the present disclosure is not limited to the above embodiment, and various modifications are possible.

For example, in the above-described embodiment, an ozone water generation apparatus that generates ozone and generates ozone water by dissolving the ozone in water is illustrated. However, the substance to be generated is not limited to ozone. Chlorous acid may be generated and used for sterilization and water treatment. It is also possible to use an apparatus for generating oxygen water, hydrogen water, chlorine-containing water, hydrogen peroxide water, and the like.

Note that these electrolytic liquid generation devices can also be used in a state where they are incorporated in other equipment and facilities. When the electrolytic liquid generation device is incorporated into another device or facility, it is preferable to arrange the electrolytic liquid generation device in an upright state with the inflow port down and the outflow port up, as in the ozone water generation apparatus 1. However, the present invention is not limited to this, and an appropriate arrangement is possible.

Further, the anode 54 can be made of a material selected from, for example, conductive silicon, conductive diamond, titanium, platinum, lead oxide, tantalum oxide, and the like, and has a conductive property capable of generating electrolytic water. Any material may be used as long as the electrode has durability and durability. When the anode 54 is a diamond electrode, the manufacturing method is not limited to the manufacturing method by film formation. Further, the substrate can be formed using a material other than a metal.

The cathode 55 may be an electrode having conductivity and durability, and may be made of, for example, a material selected from platinum, titanium, stainless steel, and conductive silicon.

Further, in the above-described embodiment, an example in which the positioning protrusion (housing protrusion) 221 extending in the stacking direction Z is provided on the peripheral wall portion 22 is exemplified, but the shape of the housing protrusion may be various shapes. . For example, a housing protrusion extending in the longitudinal direction (liquid flow direction X) may be provided at a portion of the peripheral wall 22 corresponding to the outer peripheral portion (side surface extending in the longitudinal direction) 54 a of the anode 54. . By doing so, the space S can be more reliably secured between the stacked body 51 and the peripheral wall 22 and the flow of water (liquid) in the space S is prevented from being obstructed by the housing protrusion. Can be suppressed.

ハウジング Also, the specifications (shape, size, layout, etc.) of the housing, the electrolytic section, and other details can be appropriately changed.

(Second embodiment)
Here, as a second embodiment of the present disclosure, the configuration of the laminate 51 of the ozone water generation device 1 of the present disclosure will be described in more detail.

The components described in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. The basic configuration of the ozone water generation device 1 is common to the first embodiment.

では In the above-described conventional technology, the hole formed in the cathode and the hole formed in the conductive film have the same shape. That is, the hole formed in the cathode and the hole formed in the conductive film are formed so that the contour shape and the size in plan view are the same. Then, a groove is formed by laminating the cathode and the conductive film such that the outlines of the holes overlap.

However, in the related art, when the cathode is displaced relative to the conductive film in a direction intersecting the laminating direction, the electrolytic area (contact area) between the cathode and the conductive film changes. For this reason, the current density of the current flowing through the electrolytic unit changes, and the ozone generation efficiency changes.

According to the configuration described below, it is possible to obtain an electrolytic liquid generation device capable of further stabilizing the generation efficiency of an electrolytic product.

In the following example, description will be made assuming that the anode 54 and the conductive film 56 are configured to have substantially the same projected dimensions.

Then, when the laminate 51 is formed, both ends in the width direction of the cathode 55 project outside the anode 54 and the conductive film 56 (the configuration as shown in FIG. 12).

If the both ends in the width direction of the cathode 55 are made to protrude outside the anode 54 and the conductive film 56, when the laminate 51 is accommodated in the concave portion 23, at least the inner surface 22 a of the peripheral wall portion 22 and the anode A space S is formed between the space 54 and the space 54. The space S is a space formed between the outer edge of the stacked body 51 and the peripheral wall 22 to prevent water from staying there.

れば By forming such a space portion S, it is possible to suppress the scale composed of the calcium component or the like generated by the electrolysis of water from accumulating between the laminate 51 and the peripheral wall portion 22.

Further, in the present embodiment, as shown in FIG. 12, a space S is also formed between the inner surface 22a of the peripheral wall 22 and the cathode 55.

The configuration of the laminate 51 may be based on the configuration shown in FIGS. 7 to 11 described above. That is, the basic configuration of the first embodiment can be combined with the detailed configuration described in the second embodiment.

では In the following example, the generation efficiency of ozone 70 can be further stabilized.

Specifically, the configuration (contour shape and size) of the conductive film side hole 56c and the cathode side hole 55e is different in a plan view (a state viewed along the stacking direction of the stacked body 51). ing.

(4) The conductive film side hole 56c is formed into a long and narrow hole shape in the width direction Y, and the cathode side hole 55e is formed in a V shape in which a bent portion 55f is disposed on the downstream side in plan view. Thus, the outline shapes of the conductive film side hole 56c and the cathode side hole 55e in plan view are different (see FIGS. 13 and 4).

As described above, by forming the conductive film side hole 56c in a long and narrow shape in the width direction Y, the conductive film side hole 56c is arranged in a direction (width direction Y) orthogonal to the liquid flowing direction X in plan view. It will extend (see FIG. 13). That is, the angle between the extending direction of the conductive film side hole 56c in plan view and the liquid flowing direction X is 90 degrees.

On the other hand, the cathode side hole 55e has a shape in which two long holes extending from the upstream side and the outside in the width direction Y toward the bent side 55f located on the downstream side and the center in the width direction Y are communicated with the bent part 55f. You are. That is, the two long holes extending from the bent portion 55f toward the upstream end portion 55h extend in a direction intersecting the liquid flowing direction X in a plan view (see FIG. 14).

陰極 The cathode side hole 55e is formed such that the tip end 55h is located outside the width direction on the upstream side of the bent portion 55f. Therefore, each of the two long holes constituting the cathode side hole 55e intersects the liquid passage direction X and extends in a direction intersecting the width direction Y (a direction orthogonal to the liquid passage direction X). That is, in the extending directions of the two long holes constituting the cathode side hole 55e, the absolute value of the acute angle formed by the liquid flowing direction X is larger than 0 degree and smaller than 90 degrees.

Therefore, for example, the extending direction of one long hole of the cathode-side hole 55e is a direction inclined by 30 degrees with respect to the liquid flowing direction X, and the extending direction of the other long hole is the liquid flowing direction X. A V-shaped groove that is inclined -30 degrees with respect to.

The absolute value of the acute angle between the extending direction of one of the long holes and the liquid passing direction X is equal to the absolute value of the acute angle between the extending direction of the other long hole and the liquid passing direction X. No need. That is, the shape of the cathode side hole 55e in a plan view does not need to be line-symmetric with respect to a straight line passing through the bent portion 55f and extending in the liquid flowing direction X.

In the present embodiment, in a state where the cathode 55 is stacked on the conductive film 56, the extending directions of the two long holes constituting the cathode side hole 55e are respectively equal to those of the conductive film side hole 56c in plan view. The direction is not parallel to the extending direction.

{Circle around (5)} In a state where the cathode 55 is stacked on the conductive film 56, the conductive film side hole 56c and the cathode side hole 55e are configured so as to partially communicate with each other. That is, it is configured such that a part of a plurality of long holes extending in different directions communicate with each other.

With such a configuration, the conductive film 56 and the cathode 55 are arranged such that the outer peripheral portion (contour line in plan view) 66d of the conductive film side hole 56c and the outer peripheral portion of the cathode side hole 55e (plan view) in plan view. Are stacked so as to have an intersecting portion 59 intersecting with an outline 55g (see FIG. 14).

In addition, a plurality of conductive film side holes 56c are formed in the conductive film 56 so as to be arranged in a line along the liquid flowing direction X. In the cathode 55, a plurality of cathode side holes 55e are formed so as to be arranged in a line along the liquid flowing direction X.

Two cathode-side holes 55e that are adjacent to each other in the liquid passing direction X are such that the bent portion 55f of the cathode-side hole 55e arranged on the upstream side is located on the downstream side of the tip end 55h of the cathode-side hole 55e arranged on the downstream side. It is arranged to be located. In a state where the cathode 55 is stacked on the conductive film 56, the plurality of conductive film side holes 56c are arranged so as to intersect with one cathode side hole 55e.

Accordingly, in a plan view in a state where the cathode 55 is stacked on the conductive film 56, a plurality of communication regions R1 with the conductive film side hole 56c are formed in one cathode side hole 55e, and the conductive film 56 A plurality of exposed regions R2 to be exposed are formed. That is, a plurality of intersections 59 are formed in one cathode side hole 55e.

At this time, the shape of the plurality of conductive film side holes 56c is the same, the shape of the plurality of cathode side holes 55e is the same, and the pitch of the conductive film side holes 56c in the liquid passing direction X and the cathode hole 55e are It is preferable that the pitch in the liquid passing direction X is the same.

す In this way, the communication region R1 and the exposed region R2 appear regularly along the liquid flowing direction X.

In addition, in this example, the width of the cathode 55 in the width direction Y is larger than that of the conductive film 56. Therefore, the contact area (electrolysis area) between the cathode 55 and the conductive film 56 is determined from the area of the upper surface of the conductive film 56 (the portion above the conductive film 56 where the conductive film side hole 56c is not formed). It can be approximated by a value obtained by subtracting the total area of the exposed region R2.

If the cathode 55 and the conductive film 56 are configured as described above, even when the conductive film 56 is relatively displaced with respect to the cathode 55 when forming the laminate 51, The amount of change in the contact area (electrolysis area) between the conductive film 55 and the conductive film 56 can be reduced. That is, when the positions are displaced by the same amount, the configuration shown in the present embodiment can make the amount of change in the electrolytic area smaller than the configuration shown in the above-described conventional technique.

For example, as shown in FIG. 15, when the conductive film 56 is displaced relative to the cathode 55 in the liquid flowing direction X when the stacked body 51 is formed, the area of one exposed region R2 (and (The area of one communication region R1) slightly changes near the bent portion 55f of the cathode side hole 55e. However, the area of one exposed region R2 hardly changes in other portions. Therefore, the amount of change in the total area of the exposed region R2 in one cathode side hole 55e is substantially the same as the amount of change near the bent portion 55f.

Further, in this example, even if the conductive film 56 is relatively displaced in the liquid flowing direction X with respect to the cathode 55, the outer peripheral portion of the conductive film 56 (the outline in a plan view) Line 56a contacts the cathode 55. Therefore, a change in the contact area between the conductive film 56 and the cathode 55 due to the outer peripheral portion (contour line in plan view) 56a of the conductive film 56 protruding from the cathode 55 is suppressed.

In such a configuration, the contact area of the conductive film 56 with the cathode 55 after the displacement in the liquid flowing direction X is the same as that of the conductive film 56 when the conductive film 56 is laminated at a regular position. Only slightly changes from the contact area with the cathode 55.

As shown in FIG. 16, when the conductive film 56 is relatively displaced in the width direction Y with respect to the cathode 55 when forming the stacked body 51, the area of one exposed region R2 (and 1 Basically, the area of one communication region R1 hardly changes. However, the length of the conductive film side hole 56c in the width direction Y is slightly shorter at the portion where the conductive film side concave portion 56b as the escape portion is formed, and in this portion, the area of one exposed region R2 is formed. Slightly changes.

As described above, when the positions are relatively displaced in the width direction Y, the amount of change in the total area of the exposed region R2 in one cathode side hole 55e is the amount of change in the portion where the conductive film side concave portion 56b as the escape portion is formed. It is almost the same as the amount of change.

As shown in FIG. 16, even if the conductive film 56 is relatively displaced in the width direction Y with respect to the cathode 55, the outer peripheral portion of the conductive film 56 (the outline in a plan view) Line 56a contacts the cathode 55. Accordingly, in the case of such a configuration, the contact area between the conductive film 56 and the cathode 55 after the displacement in the width direction Y is smaller than the conductive area when the conductive film 56 is laminated at a regular position. It only slightly changes from the contact area between the membrane 56 and the cathode 55.

In such a configuration, even if the conductive film 56 is relatively displaced in the horizontal direction (the liquid passing direction X and the width direction Y) with respect to the cathode 55, the contact between the conductive film 56 and the cathode 55 is prevented. Only the area changes slightly.

On the other hand, as shown in the above-described conventional technique, when a groove is formed by overlapping holes of the same shape, if the conductive film 56 is displaced with respect to the cathode 55, the conductive film 56 is formed in a normal state. Unexposed regions R2 are formed in the respective grooves.

Therefore, the total area of the exposed regions R2 formed in the respective groove portions is the amount of change in the contact area between the conductive film 56 and the cathode 55. Then, when the conductive film 56 is displaced by the same amount with respect to the cathode 55 by the same amount, the exposed region R2 newly formed in each groove portion is different from the conductive film 56 and the cathode 55 in the configuration shown in the present embodiment. Is larger than the change amount of the contact area.

For example, when the conductive film 56 is displaced in the liquid flowing direction X by the same amount with respect to the cathode 55, in the configuration shown in this embodiment, only the exposed region R2 changes near the bent portion 55f. It is. However, in the configuration shown in the related art, the exposed region R2 protruding by the amount of displacement in the liquid flowing direction X is formed almost entirely in the width direction Y of the groove 52. Thus, when the conductive film 56 is displaced by the same amount with respect to the cathode 55, the configuration shown in the present embodiment is more conductive and the cathode 55 than the configuration shown in the prior art. And the amount of change in the contact area with the contact is reduced.

Further, in the present embodiment, arc-shaped curved portions 56e are formed at both ends in the width direction Y of the conductive film side holes 56c in plan view. This prevents an edge from being formed on the outer peripheral portion (contour line in plan view) 66d of the conductive film side hole 56c.

Also, the curved portion 55f and the distal end portion 55h of the cathode side hole 55e are formed with an arcuate curved portion in plan view. This prevents an edge from being formed on the outer peripheral portion (contour line in plan view) 55g of the cathode side hole 55e.

As described above, if the outer peripheral portion (contour line in plan view) 66d of the conductive film side hole 56c and the outer peripheral portion (contour line in plan view) 55g of the cathode side hole 55e are formed in a smooth shape, the electrolytic treatment can be performed. At the time of performing, it is possible to reduce the occurrence of local electric field concentration. As a result, ozone 70 (see FIG. 13) can be more uniformly generated in the entire portion of the interface 57 exposed to the groove 52, and the generation efficiency of the ozone 70 can be further stabilized.

In the present embodiment, the groove 52 communicates with the conductive film side hole (conductive film side groove) 56c formed in the conductive film 56 and the cathode (electrode) 55 formed in the conductive film side hole 56c. And a cathode-side hole (electrode-side groove) 55e.

{Circle around (5)} The shape of the conductive film side hole 56c and the shape of the cathode side hole 55e are different when viewed along the stacking direction Z of the stacked body 51.

In this way, even if the conductive film 56 is relatively displaced with respect to the cathode (electrode) 55 in a direction intersecting the laminating direction Z, the contact area between the conductive film 56 and the cathode (electrode) 55 is reduced. Changes can be suppressed. That is, it is possible to more stably secure an electrolysis area (current-carrying area) between the conductive film 56 and the cathode (electrode) 55.

As described above, by stably securing the electrolysis area (energization area) between the conductive film 56 and the cathode (electrode) 55, the current density of the current flowing through the electrolysis unit 50 can be made more uniform. it can. That is, it is possible to suppress a change in the current density of the current flowing through the electrolytic unit 50 for each product. As a result, the generation efficiency of ozone (electrolysis product) 70 can be further stabilized.

As described above, according to the present embodiment, even when the position of the conductive film 56 and the position of the cathode (electrode) 55 are shifted, the generation efficiency of ozone (electrolysis product) 70 is further stabilized. Can be. That is, it is possible to obtain the ozone water generation device 1 in which the generation efficiency of the ozone (electrolysis product) 70 is made substantially constant.

Further, in the present embodiment, the conductive film 56 and the cathode 55 are formed such that the outer peripheral portion 66d of the conductive film side hole 56c and the cathode side hole 55e are in a state of being viewed along the stacking direction Z of the stacked body 51. It is laminated so as to have an intersection portion 59 intersecting with the outer peripheral portion 55g.

In this way, when the position of the conductive film 56 and the position of the cathode (electrode) 55 are displaced, the change in the contact area between the conductive film 56 and the cathode (electrode) 55 can be more reliably suppressed.

In the present embodiment, the conductive film side hole 56c extends in a direction intersecting with the liquid flowing direction (liquid flowing direction) X.

In this way, the ozone 70 generated near the interface 57 between the conductive film 56 and the anode 54 can be quickly peeled off from the interface 57. That is, it is possible to suppress an increase in the size of bubbles of the ozone 70 generated in the vicinity of the interface 57.

If the bubbles of the ozone 70 grow large, even if the bubbles of the ozone 70 are separated from the interface 57, they may float in the water (in the liquid) without being dissolved in the water (liquid). The dissolved concentration of the (electrolysis product) 70 may be reduced.

However, if the conductive film side hole 56c is formed so as to extend in a direction intersecting with the liquid passing direction X as in the present embodiment, the ozone 70 is quickly peeled off from the interface 57 before the bubbles grow large. be able to. As a result, the dissolution of ozone (electrolysis product) 70 in water (liquid) can be further improved.

In the present embodiment, the conductive film side hole 56c extends in a direction orthogonal to the liquid flowing direction X.

In this way, the ozone 70 generated near the interface 57 between the conductive film 56 and the anode 54 can be more quickly peeled off from the interface 57.

In this embodiment, the electrodes adjacent to each other are the cathode 55 and the anode 54. The electrode-side groove has a cathode-side hole (cathode-side groove) 55e formed in the cathode 55, and the cathode-side hole 55e extends in a direction intersecting with the liquid flowing direction X.

With this configuration, the ozone (electrolysis product) 70 can be prevented from staying in the groove 52, and the ozone 70 can be made to flow through the flow channel 11 more efficiently.

In addition, in the present embodiment, the cathode side hole 55e has a V-shape in which the bent portion 55f is arranged on the downstream side when viewed along the stacking direction Z of the stacked body 51.

In this way, the generated ozone (electrolysis product) 70 moves to the central portion where the flow velocity is relatively large along the slope of the cathode side hole 55e, and the ozone (electrolysis product) 70 stays. Can be further suppressed. As a result, the ozone concentration (electrolysis product concentration) can be further increased.

In addition, the shape of the plurality of conductive film side holes 56c is the same, the shape of the plurality of cathode side holes 55e is the same, and the pitch of the conductive film side holes 56c in the liquid passing direction X and the passage of the cathode side holes 55e are changed. It is preferable that the pitch in the liquid direction X is the same.

In this case, the communication region R1 and the exposed region R2 appear regularly along the liquid flowing direction X, so that the influence of the displacement can be reduced more reliably.

{Circle around (5)} It is preferable that arc-shaped curved portions 56e are formed at both ends in the width direction Y of the conductive film side holes 56c in plan view.

Further, it is preferable to form an arc-shaped curved portion in a plan view at the bent portion 55f and the tip of the cathode side hole 55e.

By doing so, it is possible to alleviate the occurrence of local electric field concentration when performing the electrolytic treatment, and it is possible to generate ozone 70 more evenly over the entire portion of the interface 57 that is exposed to the groove 52. Can be. As a result, the generation efficiency of ozone 70 can be further stabilized.

Further, the cathode side hole 55e is formed in a long hole shape extending along the liquid direction X so that the cathode side hole 55e and the conductive film side hole 56c intersect in a cross shape in plan view at the time of lamination. You may.

The extending direction of the conductive film side hole 56c may be a direction that intersects the liquid flowing direction X and the width direction Y (a direction orthogonal to the liquid flowing direction X). At this time, the extending direction of the conductive film side hole 56c and the extending direction of the cathode side hole 55e are made non-parallel, and the conductive film side hole 56c and the cathode side hole 55e should intersect during lamination. preferable.

The conductive film side hole 56c and the cathode side hole 55e may have a similar shape so that the entire small hole is present in the large hole during lamination.

The conductive film side hole 56c may have a V-shape, and the cathode side hole 55e may have a long hole shape.
